Use of Lisdexamfetamine Dimesylate in Treatment of Cognitive Impairment (Chronic Fatigue Syndrome): A Double Blind, Placebo Controlled Study

Rochester Center for Behavioral Medicine·interventional·Posted Feb 18, 2010·Updated Sep 9, 2025

In Brief

A Phase 4 clinical trial evaluating Lisdexamfetamine Dimesylate and Placebo "30, 50 or 70 mg" for Chronic Fatigue Syndrome and Cognitive Impairments. Completed, enrolled 26 participants across 1 site.

Detailed Summary

Over the past decade, the Rochester Center for Behavioral Medicine (RCBM) has evaluated many patients with attention deficit hyperactivity disorder (ADHD). A recurrent finding in these patients is a history of unexplained fatigue and musculoskeletal pain. Treatment of these patients in our clinic has revealed that when their underlying ADHD is treated with psychostimulant medication, many patients report significant improvements with regard to their fatigue and musculoskeletal pain. Patients report less subjective fatigue and pain and note overall functional improvement, although the initial and primary objective was the treatment of their attention or hyperactivity problems. We speculate that stimulants are efficacious by offering two distinct clinical properties. 1) anti-fatigue properties and 2) properties that allow patients to filter out extraneous stimuli (i.e. chronic muscle pain).

Interventions

Lisdexamfetamine Dimesylatedrug

Will be randomly assigned to one of two treatment arms in a 1:1 ratio of either LDX or placebo for 6 weeks. Subjects will be started with a single pill containing 30mg of LDX or comparable placebo, depending on the treatment assignment. At the week 2 visit, the dose will be increased to 50 mg (or comparable placebo) if the patient exhibits no significant adverse effects as judged by the Investigator. At the week 4 visit, the dose will be increased to 70 mg (or comparable placebo) if the patient exhibits no significant adverse effects as judged by the investigator.
